Doctor's visit

The four great cornerstones of diagnostic medicine are anatomy (structure: what is there), physiology (how the structure/s work), pathology (what goes wrong with the anatomy and physiology), and psychology (mind and behavior). In addition, the physician should consider the patient in their 'well' context rather than simply as a walking medical condition. This means the socio-political context of the patient (family, work, stress, beliefs) should be assessed as it often offers vital clues to the patient's condition and further management.

A patient typically presents a set of complaints (the symptoms) to the physician, who then performs a diagnostic procedure, which generally includes obtaining further information about the patient's symptoms, previous state of health, living conditions, and so forth. The physician then makes a review of systems (ROS) or systems inquiry, which is a set of ordered questions about each major body system in order: general (such as weight loss), endocrine, cardio-respiratory, etc. Next comes the actual physical examination and other medical tests; the findings are recorded, leading to a list of possible diagnoses. These will be investigated in order of probability.

The next task is to enlist the patient's agreement to a management plan, which will include treatment as well as plans for follow-up. Importantly, during this process the healthcare provider educates the patient about the causes, progression, outcomes, and possible treatments of his ailments, as well as often providing advice for maintaining health.

The physician's expertise comes from his knowledge of what is healthy and normal contrasted with knowledge and experience of other people who have had similar symptoms (unhealthy and abnormal), and the proven ability to relieve it with medicines (pharmacology) or other therapies about which the patient may initially have little knowledge.

Time that doctors spend with a patient.[2]

A survey in the United States came to the result that, overall, a physician sees each patient for 13 to 16 minutes.[1] Anesthesiologists, neurologists, and radiologists spend more time with each patient, with 25 minutes or more.[1] On the other hand, primary care physicians spend a median of 13 to 16 minutes per patient, whereas dermatologists and ophthalmologists spend the least time, with a median of 9 to 12 minutes per patient.[1] Overall, female physicians spend more time with each patient than do male physicians.[1]

For the patient, the time spent at the hospital can be substantially longer due to various waiting times, administrative steps or additional care from other health personnel. Regarding wait time, patients that are well informed of the necessary procedures in a clinical encounter, and the time it is expected to take, are generally more satisfied even if there is a longer waiting time.[3]

With increasing access to computers and published online medical articles, the internet has increased the ability to perform self-diagnosis instead of going to a professional health care provider. Doctors may be fearful of misleading information and being inundated by emails from patients which take time to read and respond to (time for which they are not paid).[4] About three-quarters of the U.S. population reports having a primary care physician, but the Primary Care Assessment Survey found "a significant erosion" in the quality of primary care from 1996 to 2000, most notably in the interpersonal treatment and thoroughness of physical examinations.[5]
